APPLIOATOB FOB BRAKE-DRESSING COMPOUNDS.

Application fil ed June 24, 1927. SerialNo. 201,125;

My invention relates to containers for brake dressing compounds andparticularly to an applicator for the dressing which may also be used asa clearance gauge between brake linings and drums.

In applying dressings to brake linings it has heretofore been customaryto squirt an undetermined amount of the dressing into the spaces betweenthe brake linings and drums. In applying dressing in this manner thereis a tendency to continue the application of the dressing until it dripsoff from the brake, thereby wasting an appreciable quantity of thedressing. In applying the dressing by a squirting or dripping operation,no consideration has heretofore been given the clearance existingbetween the brake drum and the brake lining. For efficient operation ofthe brake it is essential that a definite clearance be had when thebrake is in its released position.

I provide an applicator whose surface area is designed to retain theproper quantity of dressing for a single application ofthe dressing tobrake lining. In designing the area of the applicator, the viscosity ofthe dressing is considered, aswell as the actual weight of the dressingdesired in an application.' The applicator preferably comprises a flat,pliable strip of metal the thickness of which is made such as to enterbetween a brake lining and drum if the proper clearance between themexists. If the brake lining is too loose, the applicator serves toindicate the amount in which it should be drawn up. The applicator iscarried by the stopper for a dressing container and when not in useextends downwardly into the'container. The depth of the container ismade such that the applicator may reach to its bottom. I

The accompanying drawings illustrate the present preferred embodiment ofthe invention, in which, I

Figure 1 is an elevational view of a container embodying my invention;and

Figure 2 is a View, partially in elevation and partially in section, ofan applicator embodying my inventlon. 1

Referring to the drawings, the applicator is a thin strip of metalinserted in a stopper 4.,for a container 5. The applicator extendsdownwardly into the liquid brake dressing 6 in the container. 1

i In applying the liquid 6, the applicator 2 is removed from the liquidand inserted be-' tween a brake lining and drum. The amount of liquid 6adhering to the surfaces of the applicator is predetermined by theviscosity of the liquid and by the area of the applicator. Preferablythe amount is sufiicient for acomplete application of the dressing.

If the'clearance between the brake drum and lining is too small forefiioient operation of the brakes when released, the thickness of theapplicator prevents its insertion between them. If too much clearanceexists between the brake lining and drum, this condition is indicated byan excessive amount of play between the applicator 2, the lining and thedrum.

While I have shown and described the applicator as of metal, it is to beunderstood that other materials such as celluloid, and

the like, maybesubstituted therefor with out departing from the scope ofthe appended claims.

I-claim:

l. A liquid applicator comprising a thin metallic strip whose thicknessis predetermined in accordance with the clearance de sired between abrake drum and'lining.

2. A liquid applicator comprising a thin metallic strip whose thicknessis' predetermined in accordance with the clearance desired between abrake drum and lining, and Whose surface area bears a definite relationto the amount of liquid to be applied 1 to a brake lining at eachapplication.

In testimony whereof I have hereunto set my hand.

JAMES W. MOOREHEAD.
